MANURE-LOADER.

To all 'whom it may concern:

Be it known that we, CORNELIUS DIELE- MAN, l/Vmennr D. Rm'rvnnn, and JOHN D. lnrrvnLD, citizens of the United States, residing at Pella, in the county of Marion and State of Iowa, have invented a certain new and useful Manure-Loader, of which the following is a specification.

The object of our invention is to provide a manure loader of simple, durable and inexpensive construction, of the class having a receiving platform designed to receive a quantity of manure from a scraper or the like, and so arranged that when the platform is full, it may be elevated to position for dis charging in a wagon.

More specifically it is our object to provide improved means for elevating` the platform, whereby a minimum of applied power is necessary, and whereby the platform will start on its upward movement slowly, and its speed will be increased as it approaches the dumping point, so that the load upon the draft animal will be substantially equalized throughout the entire movement of the platform.

Our invention consists in certain details in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which- Figure 1 shows a side elevation of the complete device embodying our invention. The dotted lines in said figure show the platform in its elevated position ready to discharge, and Fig. 2 shows a rear end elevation of the device embodying our invention. The dotted lines in said figure show the platform in its elevated position.

Referring to the accompanying drawings, we have used the reference numeral 10 to indicate the base sills, of which there are four, and which serve as runners to support the device when being transported from place to place. Mounted upon the runners 10 is a frame, composed of four stationary uprights 11 adjacent to the rear of the runners and supported in an upright position by means of the brace beams 12 which are Specicaton of' Letters Patent.

connected to the forward end of the runners. Fixed to the forward ends of the runners is a framecomprising the uprights 13 and braces 14. This frame is designed to support two rollers 15 a suitable distance above the forward ends of the runners. Mounted in the upper ends of the rear uprights 11 is a rotatable shaft 16. Fixed to the central portion of this shaft is a large gear wheel 17, and fixed to the end portions of the shaft are the tapered drums 18. Below the central portion of the gear wheel 17 is the shaft 19 having a small gear wheel 20 fixed thereto and in mesh with the gear wheel 17, and also having a drum 21 thereon adjacent to the small gear wheel. Above the rear ends of the runners is a rail 22 having a pulley 23 connected therewith. A rope or cable 2A is fixed to and wound upon the drum 21, and is then passed through the `pulley 23, and it is intended that a draft animal be attached to the other end of the rope. Fixed to and wound upon the drums 18 are the chains 25, which chains are passed over the rollers 15, and the forward ends are attached to the platform, as will hereinafter appear.

Pivoted to the rear ends of the outer runners 10 are the arms 26 which extend forwardly beyond the runners and which su port the platform 27 at their forward en 's. Said platform lies wholly in front of the sills. Fixed to the rear edge of the platform is an auxiliary platform 28 extended upwardly and rearwardly from the platform 27, and secured in said position by means of the braces 29. When the chains 25 are wound upon the drums 18, the arms 26 and the platforms connected with them will be elevated to a substantially vertical position. In order to limit the rearward movement of the arms we have attached the brackets 30 to the uprights 11.

In order to cushion the rearward movement of the platform, and also to start the platform on its return movement after discharging its load, we have provided the following mechanism. Pivoted to the two central uprights 11 are the arms 31 extended downwardly and forwardly and resting` upon the support 32. These arms have a box 33 fixed to them to contain a Weight.

One or more chains 34 are attached to the arms 31 and also. to the platform 27, said chains being of such length that when the platform approaches a vertical position, the arms 3l and the box 33 thereon will. be elevated, as shown by dotted lines in Fig. l, and obviously the weight on said arms will tend to return the platform to starting posi.- tion. after the loadvis discharged. It is only necessary that the manure platform be started on its return movement, because afterit-i has reached a certain point in its movement, it will'return the'rest of the way by gravity.

In practical use, the platformI 27 is first filled witlrthe material to be loaded, and the platform is of such shape that a scraper full of.- manure or othermaterial may be easily run.` on itv and dumped. Wrhen` the platform is full, the draft animals attached to the scraper 2li are advanced. This will cause the drum 2ll to rotate and this inI turn will rotate'the shaft 16, on which the drums 18 are mounted. The gearing device between said shafts gives an increased leverage so that the weight of the platform and its load may be easily elevated by the draft animals. By having the chains 25woundupon tapered drums, we obtain a considerable advantage in that when the platform starts from its horizontal position upwardly, the chains wind upon the small part of thedrum, and hence the platform moves relatively slow, andy then as the elevation of the platform increases and it. becomes easier to move throughout the rest of its path,.the chains wind. upon the larger. portion of the drum, and hence the platform moves farther. In this way the weight or strain upon thedraft animals attached to the rope 24 is .made substantially uniform throughout the entire movement of the platform. Furthermore, by having the rollers l5 arranged above the pointl where the chains are attached to the platform, they chains have almost a. direct upward pull upon' the platform during the initial part ofv its movement.
